Nanocrystalline silicon substituted hydroxyapatite effects on osteoclast differentiation and resorptive activity [PDF]

open access: yes, 2014
In the present study, the effects of nanocrystalline hydroxyapatite (nano-HA) and nanocrystalline Si-substituted hydroxyapatite (nano-SiHA) on osteoclast differentiation and resorptive activity have been evaluated in vitro using osteoclast-like cells ...

Composition Restoration Enables Recycling of Mixed‐Cation, Mixed‐Halide Perovskites for Solar Cells

open access: yesAdvanced Materials, EarlyView.
Compositional drift during processing prevents the direct recycling of mixed‐cation, mixed‐halide perovskites. This work introduces a framework to quantitatively audit and restore recovered materials, enabling closed‐loop recycling with efficiencies comparable to virgin perovskites.

Conceptual design of harvesting energy system for road application [PDF]

open access: yes, 2013
Energy harvesting becomes more and more important in our life. It refers to the practice of acquiring energy from the environment which would be otherwise wasted and converting it into usable electric energy.

Mineral maturity and crystallinity index are distinct characteristics of bone mineral [PDF]

open access: yes, 2010
The purpose of this study was to test the hypothesis that mineral maturity and crystallinity index are two different characteristics of bone mineral. To this end, Fourier transform infrared microspectroscopy (FTIRM) was used.

Sea Urchin‐Inspired Immuno‐Instructive Ionic Flow Drives MSCs‐Macrophage Communication to Promote Bone Regeneration

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Bone tissue regeneration is a complex physiological process dependent on the spatiotemporal coordination of immune cells and stem cells. Conventional research primarily elucidates the mechanism through which materials facilitate bone formation by initially modulating macrophages and subsequently encouraging the osteogenic differentiation of ...

Characterization and Antimicrobial Activity of Hafnium Nanostructures Fabricated by Physical Vapor Deposition Through a Colloidal Mask

open access: yesAdvanced Materials Interfaces, EarlyView.
We generate hafnium nanostructures by first depositing polystyrene particles of varying diameter followed by physical vapour deposition of hafnium thin films. The resultant structure shows a kill‐on‐contact effect against both Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus.

Crack Repair in Hydroxyapatite Bioceramics Using an Ultraviolet Ultrafast Laser

open access: yesAdvanced Materials Interfaces, EarlyView.
The study proposes an ultrafast ultraviolet laser approach to repair hidden tooth cracks, which has been preliminarily validated on HAP. Moreover, this technique aims to strengthen the native enamel structure rather than introducing a foreign filling material.
